throttle cut out

Posted

I went camping this weekend and most of the 5 hour drive was fine. About halfway there at about 65 mph it felt like I let my foot of the pedal. It didn't die but I had to push in the clutch and rev it a few times before it came back. It happened several more times on the trip. On the way home I set my programmer back to stock and it didn't seem to do it as much (coincidence ?). Could it be the TPS or whatever its called on a dodge? Any input would be great.

Ok...

There is only 2 reason for a dead pedal.

[*]APPS sensor failure - P0121, P0122 or P0123 error code is present.

[*]VP44 failure - Might be P0216, P1688, P1689, P0251, P0252, P0253 error codes present but with a VP44 failed its not uncommon to see a VP44 fail without error codes.

So get a scan tool and check for error codes. (Key trick only work on 2000+ model years)

If your apps are bad look into timbo apps.160.00 is better than 450.00 from dealer.

    Well I got my codes read and the only code was P0216. Is there anything else I need to check like wiring or connections before condemning the pump?

    Nope... P0216 is a timing issue because the timing cam assembly is total wore out and no longer can time the pump roperly. This is cause by low fuel pressure, excessive wear internal, etc... :spend: Usually the the cheap thing that saves a pump from showing this is a fuel pressure gauge if the pressure is below 10 PSI you take a huge risk for P0216 code...

    Wonder what the longest has been for anyone to run a VP after the P0216 before it calfed completely :shrug:

    I'm probably going to find out how long it will last:pray: I guess I'll start pricing them. Who has the best price on VP44/lift pump packages?

    I ran mine with occasional P0216 for 8 months (9K miles) before it quit, and it quit fast and hard. Went from running fine to not starting at all.

    Did you get your parts yet? Hope the replacement goes well

    Not yet. Just checked UPS Tracking, parts should be here tomorrow! I'll let you know how it goes.
